More Cerny stuffs I found in GAF... he had a lot of interviews in Spanish event.

Cerny added that "first-person shooters are very important to us", and so he went to the key teams that make FPS games to ask for their feedback.

"We went to key teams who make the best of the best and we got their specific feedback on trigger springiness, concavity or convexity of joysticks and deadzones, and tuned the controller through a succession of prototypes to what it is today.

"The result is we showed at E3 and I did not hear – and it’s a tough audience – I did not hear any negative feedback about the controller."

Lead system architect Mark Cerny has revealed that, during the DualShock 4's development, Sony trialled gamepads capable of measuring players' galvanic skin response. It's a measure of how conductive your skin is at any given time, which varies based on how much you're sweating. When you're stressed, you sweat more, and that's why galvanic skin response is often used in lie-detecting polygraph tests.

"We had a long research project where we looked at pretty much any idea we could think of," says Cerny, in an exclusive conversation with Stuff. "Would it help to measure the galvanic response of the skin? We tried out a tremendous number of things - and then we went to the game teams to ask them what they thought they could use from the controller."

"Historically we have heard many times that our controllers have not been ideal for first-person shooters," he admits, "so we wanted to make sure we had something that would be much better for that genre. We tested the throw of the triggers, the position of the triggers, how much pressure it takes. We looked at the joysticks, the dead spot, we looked at convexity and concavity." The end result, he says, "feels extraordinarily natural."

Honestly the only thing I started to not like about the PS3 controller was that it is a little small. I think the bigger controller and other improvements are great and can't wait to try it out myself.

Yeah... it'll certainly be interesting to try out after a design I've been using since I was 8.

"We had a long research project where we looked at pretty much any idea we could think of,"... looking at the skin experiments, I'd say.

This is very good news. I don't mind the size of the DS3 controller, but the dead zones on those analogue sticks are really big and noticeable, especially after playing on a 360 controller, which has very small dead zones. Although it normally doesn't make a big difference in most games, having a large dead zone makes it difficult to connect precise shots as small movements on the stick are much more important.

The fact that DS4 has taken that issue into account makes me very happy. FPS games are all about the control after all.
